• Resumen

  • John Giblin of Kenyon College in Gambier OH and his student J. Tate Deskins have produced the most efficient preheating model yet by finding a way to couple the inflaton to the electromagnetic field. This dumps energy directly into photons. Their simulations show that the inflaton field could deposit 96% of its energy into photons this way. That's enough to ensure that the early universe is dominated by radiation, as predicted, says Giblin.
